Question

a cube of edge 5 cm is cut into cubes each of adge 1 centimetre find the ratio of the total surface area of one of the small cube to that of the large cube

Answer 1

Answer:

25:1

Step-by-step explanation:

surface area of cube=6a^2

hence surface area of  big cube =6*25=150

surface area of small cube =6*1=6

required ratio=6/150=1/25

Answer 2

Answer:

HOPE THIS HELPS YOU

Step-by-step explanation:

T.S.A. OF SMALL CUBE=T.S.A. OF BIG CUBE

6a²=6a²

6(1)²=6(5)²

6=6*25

6=150
